Even though the 335 in this video may have more power and torque in tuned form which the fanboys love to point out the other side of the coin is that the M3's redline and transmission are a huge advantage. Gearing is an area the M3 simply has an advantage over the 335 in and the transmission makes a big difference as one can see the shift speed in lower gears is really what gives the M3 the gains it sees in the race early on.
Up top, the tuned 335's horsepower advantage comes into play as the cars spend more time in gear negating the gear change advantage provided by the DCT allowing the 335 to inch up and close the gap.
This video is a good real world example as without race gas or meth a 335 will struggle against a tuned M3 especially one with DCT. Of course 335 owners will point out they can upgrade their turbos. Then M3 owners will say they can supercharge. Then the debate escalates and escalate and there are dozens of pages to read of M3 and 335 owners essentially throwing feces at each other. BMW fans, just enjoy 335 versus M3 round 400,000 in the video below.
M3 is the camera car.
